Application filed November 28, 1916. Serial No. 133,908.

To all whom it may concern:

Be it known that I, MARION C. WALLS, a citizen of the Unitedv States, residing at Clayton, in the county of Hendricks and State of Indiana, have invented new and useful Improvements in Pumps, 'of which the following is a specification. 1

This invention relates to pneumatic pumps and it consists in' novel features hereinafter described and claimed. n

An object of the invention is to provide a pump of'the character stated and which is automatic in its action and 'havingit's parts so arranged as to lift water successively from a plurality of cylinders whereby the water is caused to flow from the discharge pipe of the pump in a continuous stream notwithstanding the fact that the "air' is admitted alternately to these cylinders and hence one cylinder is inactivewhile the other cylinder is in active operation.

'With these objects in view'the structure comprises an inner and an outer cylinder adapted to be submerged in the'water of a well or similar container. there being valve controlled ports leading into 'bothof' the cylinders. The water pipe leads from the said cylinders and is provided with branches which enter the cylinders and ter minate at their lower ends in the'vicinity of the lower ends thereof. Air pipes lead into the upper ends of the cylinders an means are provided at the top of the well for con'trollingthe passage'of air through the said air pipewhereby the air is caused to pass'through the pipes alternately or at different intervals of time.

In the accompanying drawings Figure 1 is a side view ofthe pump'with parts brokenaway. Ti

Fig. 2 is'a fragmentary front view of the: upper portion of the same with parts shown ins'ection.

' by gravity overtlie' port detailed view 'of' parts of the' Fig. 8 is a detailed sectional view of parts ofthe pump.

The pump comprises a cylinder 1 which is adapted to be immersed in the water of a well below the surface thereof. A fitting 2 isattached' to the lower end of the cylinder 1 and is provided with a port 3. A valve 4 is' hin'ge'dly mounted in the fitting. 2 and normally rests by gravity over the port by and closes thesame. An air pipe 5 leads intothe upper end of the cylinder 1. A pipe 6 passes transverselythrough the lower por tion of the'cylinder 1 and carries a fitting 7 which communicates with the interior of the said pipe 6 to a port 8. A'valve 9 is hingedly mounted in the fitting? and normally lies 8 and closes the same? An air'pipe 10 leads into the upper end of a cylinder 11 which is mounted upon the fitting 7 and traverses the length of the upper portion of the cylinder 1. The'main or body'portion of the cylinder 11 is inclosed within the cylinder 1 as best shown in Fig. 3 of'the drawing. V

A water pipe 12 is provided at itslower end with branches 13 which enter the cyl inders 1. and'll respectively and'terminate at their'loweroendsiin the vicinity of'valves 4 and 9. The saidbranches 13- are provided with check valves 14 ofxconventional pat; tern. A casing 15 is adapted to be posi d tioned at the top of" the wclland a tank 16 is supported therein by means of rods 17.; As shown in Fig. 7 a branch pipe-'18 con-- nects atone'end with the pipe 12 and at-its other end with a valve casing 19. A'pip'e: 2G

connectsat one-end withthe pipe 12 undat its other end with the side of the casing 19 Thepipeil connects at one. end with-the casing "19 Ma point opposite the point of connection between the'pipe 20 and the said. casing and 'theother end of the said pipe 21 leads into the upper portion of thetank-16 as best shownin'Fig. 6; 7

ing' 19 and is provided'with a port-23 which at tlmes is brought'into 'rcgi'ster'with the;-

other end against the valve 22' and is under ftension "with a tendency to hold the -valve;

toward the adjacent end of the pipe18. When water isifiowingth-rough the pipe 1? the springi i holds the-ijvalve'22 ;inposi-;-

tion' against the end of the Tp1pe '18 whereby iv '100 A valve'2 2is slidablymounted in-the pas-1,

and adapted to is fixed to the the port 23 is brought into register with the pipes 20 and 21, consequently water may pass from the pipe 12 through the pipes 20 and 21 and flow into the tank 16. As soon as the flow of Water is stopped through the pipe 12 theback pressure of the water in the said pipe .is such as to cause the water in the pipe 18 to move longitudinally thereof wherebythe valve 22 is moved back against the tension of the spring 24 and the port'23 is moved out of register with the ends of the pipes 20 and 21. Thus the solid portion of the valve 22 is interposed between the adjacent ends of the pipes 20 and 21 and communication through the said pipes is interrupted, thus the fiow of the water from the pipe 12 into the tank 16 is automatically checked or stopped when the flow of water through the pipe 12 is interrupted and the water which remains in the said pipe is subjected to pressure. The pipes 20 and 21 'afiord means for supplying water to the tank 16 when the water is flowing through the pipe 12 and the pipe 18 together with the valve 22 serve asmeans for interrupting the flow of water from the pipe 12 to the tank 16 when the flow of water through the pipe 12 is stopped.

Pipes 25 depend from the bottom of the tank 16 and are provided with valves 26 of usual pattern. Clips 27 are attached to the lower portion of the pipes 25 and levers 28 are fulcrumed upon the said clips. The said levers 28 carry valves 29 located at one end close against the lower ends of the pipes 25 and the said levers 28 carry at their other ends Weights 30. The said weights 30 normally hold the valves 29 in closed position against the lower ends of the pipes 25.

A shaft 31 is mounted below the tank 16 and a bar 32 is mounted upon the said shaft for turning movement about the axis thereof. The said bar 32 carries at its ends outstanding pins 33 and the inner weighted ends of the levers 28 are located in the paths of movement of the said pins. An arm 34 shaft 31 and the bail handles of buckets 35 are pivotally connected with the ends of the said arms 34. The pins 33, hereinbefore described, extend transversely across the paths of movement of the end portions of the arms 34. The buckets 35 are mounted at their bottoms with nipples 36and valves 37 normally rest upon the upper ends of the said nipples and close the same. The stems 38 pass through the nipples 36 and project below the lower ends thereof. Disks39' are mounted upon the intermediate portions of the stems 38 and are normally spaced from the lower ends ofthe nipples 36.

Thebottom of the casing 15 is provided with openings 40, best shown in Fig. 2 through which the lower- 37 is moved portions of thd casing whereby the valve stem 38 is moved longitudinally in the nipple 36 and the valve to an open position as shown at the left in Fig. 2. Therefore any water which has been poured into the bucket 35 may escape through the nipple and flow through the opening 40 out of the casing 15.

When the bucket 35 is at its lower position as shown at the left in Fig. 2 the valve 29 above the said bucket is in closed position against the lower end of the pipe 25 above the said bucket, but it will be observed that.

the pins 33 at the right hand end of the bar 32 is in contact with the longer end of the lever 28 at the right of the said figure consequently the valve 29 is in an open posi-' tion below the pipe 25 and the water may flow from the tank 16 through the pipe 25 at the right of the said tank and enter the bucket 35 below. A weight 41 is mounted upon the intermediate portion of the arm 34 and is adapted to swing transversely across a plane passing vertically through the axis of the shaft 31 as the said arm WVhen a quantity of water has been accumu 34 swings;

lated in the bucket 35 at the right sufi'icient to overcome the weight 41 the bucket 35 at r the right descends and the bucket-35 at. the left ascends. This causes the arm 34 to swing whereby the weight 41 is carried fromone side of the vertical plane passing through the axis of the shaft 31 to theopposite side of the said plane. As the left hand end of the arm 34 moves in an upward direction it encounters the pin 33 just above the same and the'bar 32 is swung whereby the pin at the right hand end of the said bar is moved below the weighted end ofthe lever 38 at the right hand side of the figure and the valve 29 at the right hand side of the figure assumes the closed position at the lower end of the pipe 25 just above. lVhen the pin 33 at the left hand of thebar 32 strikes the lever 28 at the left of the said figure the said lever is swung whereby the valve 29 carried by the same is moved from under the lower end of the pipe 25 and therefore the a seat 44 and a Valve 45 is located in the lower portion of the pipe 43 and is adapted to engage at its upper end the seat 44 when the parts are in positions as shown in Fig. 4 of the drawing. The upper end of the pipe 5 communicates with the interior of the pipe 43 by means of a branch 46, the said branch 46 joining with the pipe 43 at a point between the ends of the valve 45. The lower portion of the valve 45 projects below the lower end of the pipe 43 and is provided with a loop 47. The upper end of the pipe 10 communicates with the interior of the pipe 43 through the sides thereof and the valve 45 is provided with a port 48 adapted to be brought into register with the upper end of the pipe 10 when the valve 45 is in its elevated position in the pipe 43.

A casing 49 is mounted at the lower end of the pipe 42 and communicates with the same through ports 50 and 51. A pipe 52 is connected at one end with the casing 49 at a point opposite the port 50 and the said pipe 52 at its other end is connected with the upper end of the pipe 5. A pipe 53 is connected at one end with the casing 49 at a point opposite the port 51 and at its other end with the upper portion of the pipe 10. A valve 54 is sl dably mounted in the casing 49 and is provided at its lower end with an eye or loop 55. The said valve 54 is further provided with ports 56 and 57 which are spaced from each other a distance greater than the distance between the ports 50 and 51 hereinhefore described. A bar 58 is fixed to the shaft 31 and passes through the loops 47 and 55 as most clearly indicated in Fig. 4 of the drawing.

Assuming that the parts are in position as shown in Fig. 4 of the drawing the operation of the pneumatic features of the device is as follows Compressed air ispassed through the inlet pipe 42 and in view of the fact that the port 51 is in register with the port 50 the air passes from the said pipe through the said ports and the pipe 52 into the upper end of the pipe 5. It will be observed that the valve 45 is in a closed position across the end of the branch pipe 46 mounted at the upper end of the pipe 5. The compressed air passes down the pipe 5 and enters the upper end of the cylinder 1. In view of the fact that the said cylinder is submerged below the surface of the water, the water which is in the cylinder is forced in a downward direction and up through the branch pipe 13 which enters the cylinder 1 and the pipe 12 and out at the upper end thereof. During this time the port 48 is in register with the upper end of the pipe 10 as shown in Fig. 4 and the air from the cylinder 11 may exhaust through the pipe 10 and pass through the port 48. Thus the water may flow through the pipe 6 and the fitting 7 into the cylinder 11. \Vhen the cylinder 1 is emptied and the cylinder 11 is filled with water the shaft 31 is turned as hereinbefore described. Thus the valve 45 is moved away from the seat 44 and the air may exhaust from. the cylinder 1 through the pipe 5 and branch 46 and pipe 43. WV hen the said valve 45 is lowered in the pipe 43 the port 48 is carried below the upper end of the pipe 10 and consequently the upper end of the said pipe is closed. When the valve 54 is elevated in the casing 49 the port 57 is brought into register with the port 51 and the end of the pipe 53 and the port 56 is moved out of register with the port 50 and the end of the pipe 52. Consequently the air may pass from the pipe 42 through the port 51 and port 57 and pipe 53 into the pipe 10 and en.- ter the upper portion of the cylinder 11 and force the water from the said cylinder. The said water passes from the cylinder 11 up through that branch 13 which enters the same and out through the pipe 12.

Therefore it will be seen that the cylinders 1 and 11 are adapted to take in the water at alternate intervals and the air operating upon the water so admitted into the cylinders forces the same from the cylinders at alternate intervals thus the said water passes out through the same pipe in the form of a continuous stream.
